This work investigates the dynamics of dual-drop impact on a solid surface, encompassing both simultaneous and nonsimultaneous side-by-side impact of equal-sized drops, as well as successive impact of unequal-sized drops. Numerical simulati...

We study the thermodynamic cost associated with driving systems between different nonequilibrium steady states. In particular, we combine a linear-response framework for nonequilibrium Markov systems with Lagrangian techniques to minimize t...
Three-body interactions unveil devil's staircase, multistability, and synchronization revival in phase oscillators [0.03%]

Synchronization in systems with higher-order interactions remains a frontier in understanding collective behavior beyond pairwise coupling. This study investigates a minimal model of three nonidentical phase oscillators governed by pure thr...

Triadic interactions are special types of higher-order interactions that occur when regulator nodes modulate the interactions between other two or more nodes. In the presence of triadic interactions, a percolation process occurring on a sin...

Elastic interfaces in quenched random media driven by external forces exhibit a continuous depinning phase transition between pinned and moving phases at a critical external force. Recent work [Phys. Rev. Lett. 129, 175701 (2022)10.1103/Phy...

Spatiotemporal chaos in systems such as turbulent flows often resides on finite-dimensional attractors, enabling the construction of reduced-order models. Unfortunately, as the dimension of these attractors increases it becomes more difficu...
Particles, trajectories, and diffusion: Random walks in cooling granular gases [0.03%]

We study the mean-square displacement (MSD) of a tracer particle diffusing in a granular gas of inelastic hard spheres under homogeneous cooling state. Tracer and granular gas particles are in general mechanically different. Our approach us...

Designing stable cluster synchronization patterns is a fundamental challenge in nonlinear dynamics of networks with great relevance to understanding neuronal and brain dynamics. So far, cluster synchronization has been studied exclusively i...
Change in the order of a phase transition in the two-dimensional Potts model with equivalent neighbors [0.03%]

Two-dimensional (2D) Potts model is a classical example when the symmetry of the order parameter controls the order of a phase transition: on a square lattice with nearest-neighbors interaction, when the number of states q is less than or e...
